Small and micro fault fusion identification method based on five-dimensional data

The invention provides a five-dimensional data-based small and micro fault fusion identification method. The method comprises the steps of S1, acquiring seismic data through wide-azimuth acquisition and a variable-surface-element high-density wide-azimuth three-dimensional seismic acquisition technology; s2, five-dimensional data dominant gather azimuth data meeting preset conditions are divided; s3, guiding a small and micro fault identification technology based on a geological comprehensive mode of five-dimensional data; and S4, describing the small and micro faults based on multidirectional attributes adopted by the five-dimensional data, and completing plane combination of the small and micro faults. The invention provides an integrated optimization fusion method based on high-density wide-azimuth seismic acquisition, five-dimensional data processing and interpretation and fine description of multi-azimuth data small and micro faults, the small and micro faults can be effectively identified, a complex sma
